OPA727AIDRBT

Texas Instruments · Precision Op Amps · SON-8-EP(3x3)

OPA727AIDRBT from Texas Instruments, in a SON-8-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection.
2 -IN input Inverting input of the amplifier; input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be current limited to 10mA or less.
3 +IN input Non-inverting input of the amplifier; input common-mode range extends from V- to (V+) - 2.5V and signals more than 0.5V beyond the rails should be current limited to 10mA or less.
4 V- power_in Negative supply (or ground in single-supply operation); the exposed thermal die pad must also be connected to V-.
5 NC unconnected No internal connection.
6 OUT output Amplifier output with rail-to-rail swing, within 150mV of the rails for light loads (>100kΩ) and within 250mV with 1kΩ loads.
7 V+ power_in Positive supply, specified for 4V to 12V total supply (absolute maximum 13.2V) and to be bypassed with 1nF ceramic in parallel with 1µF tantalum capacitors.
8 NC unconnected No internal connection.
9 EP power_in Exposed thermal die pad on underside, to be connected to V- and soldered to the PCB thermal pad.

CAD (KiCad official)

  • Symbol: OPA727AIDRBT
  • Footprint: Package_SON:WSON-8-1EP_3x3mm_P0.5mm_EP1.6x2.0mm
  • 3D model: SON-8-EP(3x3) (KiCad packages3D, STEP)
  • 3D model files: opa727aidrbt-etched.step / opa727aidrbt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa727aidrbt.step / opa727aidrbt.glb are the bare package body.
